# PP-TinyPose Python Deployment Example
|
||
|
||
Before deployment, two steps require confirmation
|
||
|
||
- 1. Software and hardware should meet the requirements. Please refer to [FastDeploy Environment Requirements](../../../../../docs/en/build_and_install/download_prebuilt_libraries.md)
|
||
- 2. Download the precompiled deployment library and samples code according to your development environment. Refer to [FastDeploy Precompiled Library](../../../../../docs/en/build_and_install/download_prebuilt_libraries.md)
|
||
|
||
This directory provides the `Multi-person keypoint detection in a single image` example that `pptinypose_infer.py` fast finishes the deployment of PP-TinyPose on CPU/GPU and GPU accelerated by TensorRT. The script is as follows
|
||
>> **Attention**: single model currently only supports single-person keypoint detection in a single image. Therefore, the input image should contain one person only or should be cropped. For multi-person keypoint detection, refer to [PP-TinyPose Pipeline](../../det_keypoint_unite/python/README.md)
|
||
|
||
```bash
|
||
# Download the example code for deployment
|
||
git clone https://github.com/PaddlePaddle/FastDeploy.git
|
||
cd FastDeploy/examples/vision/keypointdetection/tiny_pose/python
|
||
|
||
# Download PP-TinyPose model files and test images
|
||
wget https://bj.bcebos.com/paddlehub/fastdeploy/PP_TinyPose_256x192_infer.tgz
|
||
tar -xvf PP_TinyPose_256x192_infer.tgz
|
||
wget https://bj.bcebos.com/paddlehub/fastdeploy/hrnet_demo.jpg
|
||
|
||
# CPU inference
|
||
python pptinypose_infer.py --tinypose_model_dir PP_TinyPose_256x192_infer --image hrnet_demo.jpg --device cpu
|
||
# GPU inference
|
||
python pptinypose_infer.py --tinypose_model_dir PP_TinyPose_256x192_infer --image hrnet_demo.jpg --device gpu
|
||
# TensorRT inference on GPU(Attention: It is somewhat time-consuming for the operation of model serialization when running TensorRT inference for the first time. Please be patient.)
|
||
python pptinypose_infer.py --tinypose_model_dir PP_TinyPose_256x192_infer --image hrnet_demo.jpg --device gpu --use_trt True
|
||
# KunlunXin XPU inference
|
||
python pptinypose_infer.py --tinypose_model_dir PP_TinyPose_256x192_infer --image hrnet_demo.jpg --device kunlunxin
|
||
```
|
||
|
||
The visualized result after running is as follows

## PP-TinyPose Python Interface
|
||
|
||
```python
|
||
fd.vision.keypointdetection.PPTinyPose(model_file, params_file, config_file, runtime_option=None, model_format=ModelFormat.PADDLE)
|
||
```
|
||
|
||
PP-TinyPose model loading and initialization, among which model_file, params_file, and config_file are the Paddle inference files exported from the training model. Refer to [Model Export](https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.5/deploy/EXPORT_MODEL.md) for more information
|
||
|
||
**Parameter**
|
||
|
||
> * **model_file**(str): Model file path
|
||
> * **params_file**(str): Parameter file path
|
||
> * **config_file**(str): Inference deployment configuration file
|
||
> * **runtime_option**(RuntimeOption): Backend inference configuration. None by default, which is the default configuration
|
||
> * **model_format**(ModelFormat): Model format. Paddle format by default
|
||
|
||
### predict function
|
||
|
||
> ```python
|
||
> PPTinyPose.predict(input_image)
|
||
> ```
|
||
>
|
||
> Model prediction interface. Input images and output detection results.
|
||
>
|
||
> **Parameter**
|
||
>
|
||
> > * **input_image**(np.ndarray): Input data in HWC or BGR format
|
||
|
||
> **Return**
|
||
>
|
||
> > Return `fastdeploy.vision.KeyPointDetectionResult` structure. Refer to [Vision Model Prediction Results](../../../../../docs/api/vision_results/) for the description of the structure.
|
||
|
||
### Class Member Property
|
||
#### Post-processing Parameter
|
||
Users can modify the following pre-processing parameters to their needs, which affects the final inference and deployment results
|
||
|
||
> > * **use_dark**(bool): • Whether to use DARK for post-processing. Refer to [Reference Paper](https://arxiv.org/abs/1910.06278)
